i didn't really have a problem with the fade. I honestly thought you meant the 80's disco icon.
I thougt the Orzammar part was way,way,WAY more tedious, boring segments, an overhanging sence of frustration and annoyance and thge feeling of doing everything over aand over in an extended excercise in futility. But i suppose that was supposed to feel like that, furthering the sense of dread, frustration and hatred that the dwarfes have against venturing into the deep roads.
My problem with the fade (now that i think about it seriously) is that it felt,gimmicky, use this power to go here, do that lever puzzle here. Oh, all those skills you've been cultivating? nope, don't use those, your build is pointless here.
On the other hand, it's been proposed that i did the world map in the wrong order, but dammit, it's open worlded, it's not supposed to be done in the wrong order.
